As connected with the voyage of the Herald, it raiiy be proper 

 to add^ that Mr. J. Goodridge, surgeon, found a Mainillaria on the 

 island of Cerros, east of California, which was by me forwarded to 

 Prince Salm-Dyck, unfortunately in a very imperfect state. It has 

 been placed by him under his Mamillarix heterochlorse, page 10 of 

 his enumeration, and is described by him as Mamillaria Goodridgii 

 Scheer, thus: >i< * * "The prince seems to think, that it ap- 

 proaches to M. Betieckei, Ehrenb, but that, on comparing the 

 actual plants, does not appear to me to be the case. About Guay- 

 mas a Marnillaria somewhat similar to M. Goodridgii was found, 

 but more like a Mamillaria angzcinea, with a central spine strong 

 and hooked ; also a very robust species of Mamillaria sphacelata^^ 



"The cactus family [on Cedros Island] was represented by some 

 four or five species; among them a giant cereus and a very minute 

 species of Mamalaria, with a disproportionately large flower, ex- 

 ceedingly fragrant." Report of Dr. John A. Veatch in Ross Browne's 

 Sketch of Lower California, p. 152, 1869. 



The foregoing was until three years ago the sum of our knowl- 

 edge of M. Goodrichii. It will be noticed^ that Scheer corrects 

 Salm-Dyck's "Corros" but himself locates the island to the "east" of 

 California. In both cases these were probably errors of the printer. 

 It is unfortunate, that the name was originally printed Goodrichii, as 

 it gives room for difference between those^ who rigidly adhere to a 

 name as it first appears, and those^who would correct obvious errors. 



The plant of Scheer was brought from Cedros Island by Captain 

 Porter in 1894 and the next year from La Paz; from San Martin 

 Island by A. W. Anthony in 1896 ; from San Jose del Cabo by T. 

 S. Braudegee in 1893 and from Natividad Island in 1897. Dr. 

 Palmer's No. 693 from Cedros Island, not seen, may belong here.
